细菌是无处不在的,而且随着其耐药性的日益增强,治疗难度也逐渐加大,因而设计新的方法抑制其耐药性已刻不容缓。抗生素的作用靶标主要有三种类型:干扰细胞壁的合成;抑制蛋白质的合成;抑制DNA复制所需要的酶类。专家认为抗生素作用的靶标较少,因此研发新的抗生素也更加困难。最 Bacteria are ubiquitous, and as their drug resistance increases and the difficulty of treatment increases, it is imperative that new methods be designed to inhibit their resistance. There are three main types of antibiotic targets: interfering cell wall synthesis, inhibiting protein synthesis, and enzymes that inhibit DNA replication. Experts believe that the role of antibiotics fewer targets, so the development of new antibiotics is also more difficult. most
